Initial Server Setup with Ubuntu 16.04

If you've just spun up a new Ubuntu 16.04 server, the first thing you'll want to do is set it up to be secure and ready to use. This tutorial will guide you through the steps necessary to perform the initial server setup.

Step 1: Update and Upgrade Packages

The first step in setting up your server is to update and upgrade the packages that are installed. To do this, log in to your server and run the following commands:

sudo apt-get update
sudo apt-get upgrade

Step 2: Create a New User

By default, your server will come with a root user account. It's not recommended to use the root account for everyday tasks, as it can be dangerous if you make a mistake. Instead, you should create a new user account and use that for everyday tasks.

To create a new user, run the following command:

adduser username

Replace username with the name of the user you want to create.

Step 3: Grant Sudo Privileges to the New User

Once you've created a new user, you should give them sudo privileges so they can run administrative tasks. To do this, run the following command:

usermod -aG sudo username

Replace username with the name of the user you just created.

Step 4: Set Up a Basic Firewall

A firewall is a tool that can help secure your server by controlling incoming and outgoing traffic. Ubuntu comes with a firewall tool called ufw (Uncomplicated Firewall) that is easy to use. To set up a basic firewall, run the following commands:

sudo ufw allow OpenSSH
sudo ufw enable

The first command allows incoming SSH connections, and the second command enables the firewall.

Conclusion

By following these steps, you should have a basic understanding of how to perform the initial server setup on Ubuntu 16.04. This will help you get your server up and running quickly and securely.
